JAMES C. HOLLOWVAY, OF SAN FRANCISCO, OALIFORNTA.

OATMEALJVlACi-HNE.

SPECIFICATION forming part of Letters Patent No. 324,556, dated August 18, 1885.

Application filed May 11, 1885. (No model.)

To aZZ 1071/0172 it may concern:

Be it known that I, J arms 0. HOLLOWAY, of the city and county of San Francisco, and State of California, havcinvented an Improve ment in Oatmeal-Machines; and I hereby declare the followingto be a full, clear, and exact description thereof.

My invention relates to that class of oatmealmills in which a rotating perforated rim is adapted to cut the oats against an exterior annular series of knives; and my invention consists in the devices hereinafter described and claimed.

The object of my invention is to provide a simple, effective, and rapidlyworking out meal-mill of great capacity.

Referring to the accompanying drawings, Figure l is a perspective view of my mill, several parts being broken away to show interior portions. Fig. 2 is a vertical section of same on a smaller scale.

A is the frame or stand of the mill, on top of which is a plate, B, having an upwardlyextending flange, b, to which the annular series of knives G are secured. The knives have cutting-edges on each side, which are separated sufficiently to permit the egress of the cut oats or grain.

D is a vertical shaft suitably stepped in the base of the stand, and journaled in the top plate, B. It carries on its top a head, E, on the periphery of which is formed or secured the perforated rim or flange F, which lies just within and is concentric with the annular se ries of knives. The head E also carries radial arms or wings e, which extend from its central upwardly-projecting hub, e, and stop short of the perforated rim.

G is a cap-plate, on the under surface of which is secured an annular flange, H, the outer surface of which is provided with a series of parallel-spaced ribs, h, which, though they may be straight, are preferably arranged in an inclined or angling position, in order to produce a better feeding effect. The cap fits and rests upon an exterior shell or curb, I, which encircles the knives, though separated therefrom, leaving an annular discharge-chamher, i, and rests upon a rabbet formed on the top plate, B. When the cap-plate is in posi tion, the flange H. lies within the perforated rim and just beyond the ends of the wings e, and the depth of the flange is such that its lower edge does not touch the surface of the head E, but lies just above it, leaving a small feed-space for the cats to pass from within under the flange and into the space between the flange and perforated rim, which space is oc copied by the inclined or angling ribs, Fig. 2. The center of the cap-plate is provided with an aperture, 9, which communicates with the the feed space or chamber 6 inclosed by the flange H, of which space the head E forms the floor. .Into this aperture is let a feed-hopper, J, the neck of which lies just above the hub e of the head. By pushing the hopper down so that its nccl: rests upon the hub, the feed may be entirely out off; and by raising it to different points the amount of feed may be regulated and controlled. The upper edge of the perforated l'llll rises just above the knives, and is provided with stirrcrs or wipers K, which consist of small bars extending downwardly into the space inclosed by the outer shell or curb, and provided with feet It, which travel just above the top plate, 1-3.

L is the discharge chute communicating with the dischargechamber.

M is a pulley on shaft D, by which it is driven.

The operation of the mill is as follows: Suitable power is applied to shaft D to rotate it, whereby the head E and its perforated rim F are rotated. The knives G are stationary, as are the ribs 71.. The oats are fed into hopper J, and thence pass through the center of the cap-plate G into the feed-chamber 0. Here, under the influence of centrifugal force, assisted by the positive action of the wings e, and also by the outward blast from within, caused by the rapidly-rotating wings, the oats pass under the stationary flange H into the space between said flange and the perforated rim. In this space they encounter the stationary angling or inclined ribs, against which, on account of their inclination, the oats rise up, spreading themselves out and presenting themselves to the perforated rim over its entire surface. This is ofgreat advantage in causing an equal wear upon the perforated rim, but more especially in bringing all of its surface into action. The oats, projecting through the perforations of the rotating rim, are out against the knives, the cut sections dropping out between said knives into the discharge-chamber. Here they are met by the wipers, and are forced into the dischargechute. It will be noticed that in this mill the feed and passage of the oats are. continuous, and distributed throughout the entire circle. This increases the capacity of the machine materially, and avoids any clogging. The feed is, moreover, rapid, each oat finding its passage in the most direct manner. v

The parts are so constructed and put together that any portion of the mill may be easily reached; but this is especially true of the knives, which can be adjusted readily by removing the outer shell and watching where they may need alteration while the head E is rotating.

I am aware that an annular rotating perforated rim, concentric. with an annular series of fixed knives, is notnew, and-I do not claim such, broadly; but

What I do claim as new, and desire to secure by Letters Patent, is-

1. In an oatmeal-machine, a fixed annular series of knives and a rotating headhaving an upwardly-extending-perforated annularflange lying within the circumference of the knives, in combination with a fixed annular flange having on its outer surface a series of parallel inclined or angling. ribs, said flange being within the circumferenceof' the perforated-rim and having its lower edge raised above the surface of the head, whereby a passage is left for the oats, substantially as herein described.

2. In an oatmeal-mill, a rotating head provicled with an annular perforated rim and a fixed annular series of knives exterior to the rim, in combination with an annular flange provided with parallel-spaced ribs on its outer surface, said flange and ribs lying within the circumference of the perforated rim and having its lower edge raised above the head, to provide a passage forlthe oats, and means for feeding the oats into the space inelosed by the flange, substantially as herein described.

3. In an oatmeal-mill, the combinatiouofa the top plate, B, having the series of knives O,

the rotatinghead E, havinga perforated rim, F, lying within the knives, the outer shell or curb, I, resting on the top plate and forming a discharge-chamber between itself and theknives, the centrally-perforated cap-plate G, resting on the outer shell, and the downwardly-extending flange H onthe cap-plate, having a series of inclined or angling ribs, h, on its outer surface, said flange lying within the circumference of the perforated rim and having its lower edge raised above thehead, substantially as herein described.

5. An oatmeal-mill, comprising the top plate, B, having the fixed annular series of knives G, the outer shell or curb, I, encircling the knives and forming a discharge-chamber, i,adischarge-chute, L, the rotatinghead E,ha:ving an annular perforated rim, F, within-the circumference of theseries of knives, thecentrally-perforated cap-plate G, resting on the outer shell and having an annular flange, H, provided; with angling ribs h on its outer s-u-rface,said flange lying within the circumference of the perforated rimv and having its-lower edge raised above the head, and the hopper J,fitted in the center of the cap-plate, all arranged and; adapted to operate, substantially as herein described.

In witnesswhereof I have hereunto set my hand.
